JOHN W'M. DOBSON, OF SALT LAKE CITY, UTAH.

RUDDER..

SPECIFICATION forming part of Letters Patent No. 594,068, dated November23, 1897. Application filed October 31, 1896. Serial No. 610,757. (Nomodel.)

To all whom it may concern:

Be-it known that 1, JOHN WM. DoBsoN, a citizen of the United States,residing at Salt Lake City, in the county of Salt Lake and State ofUtah, have invented certain new and useful Improvements in Rudders; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to rudders for boats, the same being especiallyapplicable to use upon racing boats and yachts, the prime object of thesame being to produce a rudder which when the helm is hard down willpresent no angles which will retard the speed of the boat and willreduce the draw-back tendency due to eddying suctions to a minimum.

The invention consists of a rudder made of vflexible material, securedtothe under side of the stern of the boat at its forward end, an armpivoted to the rear end of the rudder and extending forwardly therefrom,a cross-bar pivoted to a stationary part of the hull, to which said armis secured, tiller-ropes connectedto the outer ends of said cross-bar,and a handle upon said arm, whereby the rudder may be operated directlyby hand.

The invention also consists in other details of construction andcombinations of parts, which will be hereinafter more fully describedand claimed.

In the drawings forming part of this specification, Figure 1 representsa side elevation, partly broken away, of the rear end of the hull of theboat with my improved flexible rudder applied thereto. Fig. 2 is a rearelevation of the same. Fig. 3 is a similar view showing the rudder insteering position. Fig. 4 is a top plan view of the hull of the boatwith my improved rudder applied.

Like reference-numerals indicate like parts in the different views.

My improved rudder 1 is permanently secured at its forward end to thehull 2 of the boat, as clearly shown. In large vessels the rudder 1would be completely submerged but in smaller vessels the upper endthereof will project slightly above the surface of the water. The saidrudder is preferably constructed of flexible steel, so that the rearfree end thereof may be turned in one direction or the other forsteering purposes. When thisis done, it will be seen that no sharpangles are produced between the extreme stern of the boat and the rudderwhich will tend to retard the motion of the vessel, and, furthermore,eddying suctions having the same eifect are reduced to a minimum.Pivoted at a point near the rear end of the rudder 1 is an arm 3, whichextends forwardly and is connected at its front end to a cross-arm 4,which is itself pivoted at its central point to the hull 2. Anoperating-handle 5 may be secured to the upper side of the arm 3 toprovide means for turning the rudder directly by hand. Upon a smallerboat the outer ends of the cross-arm 4 will have attached to themtiller-ropes 6 6, extending forwardly therefrom.

Myimproved rudder is operated in the same manner that ordinary ruddersare, either by means of the handle 5 or the tiller-ropes 6 6, connectedto the cross-arm 4.

The device is extremely simple in'construction and effective inoperation especially upon 7 5 racing-craft, where it is the desideratumto present as free and smooth a surface to the water as possible.

Having now described my invention, what I claim as new, and desire tosecure by Let- 8o ters Patent, is

1. The combination with the hull of a boat, of a flexible ruddertherefor fixedly secured at its forward end to the stern of the boat.

2. The combination with the hull of a boat,

of a rudder constructed of steel or other suitable flexible materialfixedly secured at its forward end to the boat, and means for bendingsaid rudder.

3. The combination with the hull of a boat, of a flexible ruddertherefor, an arm pivoted at its rear end to the free end of said rudderand extending forwardly therefrom, and means for turning said arm,substantially as and for the purpose described.

4. The combination with the hull of a boat, of a flexible ruddertherefor secured at its forward end to the stern of said boat, an armpivoted at its rear end to the free end of said rudder and at itsforward end to a stationary part of said boat, and a handle upon saidarm, substantially as and for the purpose described.

r 5. The combination with the hull of a boat, In testimony whereof Ihave signed this of a flexible rudder therefor secured at itsforspecification in the presence of two subscrib- 1o ward end to thestern of said boat, an arm ing witnesses.

pivoted at its rear end to the free end of said V rudder and connectedat its forward end to a JOHN DOBSON' cross-bar pivoted to the stationarypart of said WVitnesses:

boat, and means for swinging said cross-bar, J. C. JENSEN,

substantially as and for the purpose described. ARTHUR F. BOWYER.
